you might want to check if there's the directory first,
or if there's a way to tell find to be quiet or ignore that

find: ‘pmu-events/arch/x86’: No such file or directory
  CC       pmu-events/json.o
  CC       pmu-events/jsmn.o
  CC       pmu-events/jevents.o
  LD       pmu-events/jevents-in.o
  LINK     pmu-events/jevents
find: ‘pmu-events/arch/x86’: No such file or directory
pmu-events/jevents: Error walking file tree pmu-events/arch/x86
